WARP GONDE'NSER.

Application filed. September 15-,` 1923.

T01 all whom it may concern.'

Be it known that I, STUART 7. CRAMER, Jr., a citizen of the United States, andl a residentoi Philadelphia, countyof Philadelphia, State ot Pennsylvania, have invented certain new and useful Improvements in larp Condensers, of which the following is a speciiication.

This invention relates to a method and apparatus for coiling yarn preparatory to dyeing it and, more particularly,` to a method of andapparatus for ceiling warps of yarn or thread in sucha manner that a long chain or length of warp may be withdrawn fromthe coils in a number of connected shorter strands or loops in convenient. relation to be passed through a dye vat.

The type of warp dyeing known as. long chain dyeing provides an inexpensive method ot-dyeingbut does not iin all cases produce results of the uniformity obtainable in short chain vats owing to the largenumber of ends contained-in a single bunch or tothe exhaustion of the dye liquor towards the latter portion of the long chain.

An object ot the present invention is to provide a method of handling warp so that a long chain of the warp may be dyed in a short chain vat.

Another object of the invention is to provide a method of coiling warpl so that a long chain of the warp may be drawn out in a number of connected loops or strands.

A further object of the invention is to' provide an apparatus in which warp may be coiled in such a manner as' to be drawn out 'in a number of loops or strands in suitable position-tor passing through a dye tank or vat.

A further object of the invention is to provide an apparatus in which any rope or strand may be coiled in such a manner as to be drawn out in such Jforni that its thickness' r varies with the. number ot coils employed,VV

while its length will vary inversely with that number.

Further objects of the invention are' to provide an apparatus in which warp may be coiled in coils alternately built up from opposite ends and'connected atalternately opposite ends, to provide an apparatus having warp coil receptacles which may be rotated to be illed alternately from opposite ends' Seria-1- NO. 662,829.

and tov provide warp. receivingcans whicl'i` may be iilled from either end.

j 'With these and other objects in view, the invention comprises the method and apparatus described and set forth in the follow-y ingspecication and claims;

The various features of the invention areillustrated in the accompanying drawings in which: Y

Fig. 11 is a vertical sectional view ofthe apparat-us taken on line ll-l of Fig. 9, and,

Fig. 12 is a detail'view of a cover forming part of the apparatus of Figs. 9-ll- In my present invention the warp is coiled in an end can or receptacle of a series of warp receiving cans, the coil beingfbuilt upwardly from the bottom of the receptacle to the top. `The warp is. then continued out through a longitudinal slot to the top` of thenext adjacent can from which the lid and bottom have been removed and i-s insertedY in the upper part of this'second can through a similar longitudinal slot. A 'cover is then placed on the secondV can and the cansare then rotated about al horizontal axis" to invert them and bring the tops to the bot*- tom or underneath position and the warp is H individual cans.

`the' number of cans filled depending on the length of the warp and on the number and length of the separate coils desired.k There is thus formed a continuous warp consisting of a number of separate coils alternately7 built up from opposite directions and connected alternately at opposite ends. When the cans are in uprightposition and the up per connecting portions of the warp are drawn outthe warp forms into a combined .rope made up of ka number of strands or loops of substantially identical length which may be easily passed through a short chain dye vat, or other apparatus in which it is desirable to have a chain of less length than f1the*original-warp, without unduly increasing-its thickness.

Referring more particularly to the ac companying drawings, a warp 14 is coiled from a spout 15 into an'end can 16, of a .series of cans 16, 18, 20, 22, 24 and 26,

rotatably supported on end members 23 and 30, of a supporting frame 32 in such a manner as to be rotatable on a horizontal axis at right vangles to the central axes of the The coil of warp is built up in the firstrcan 16 until the top of the can is reached and is then carried through. a slot 34, extending longitudinally of the surface of the can, to the top of the adjacent can 18, from which the bottom cover has been removed, and is inserted through a similar longitudinal slot 36. Covers 37 and 38 are then placed on the tops of the first and second cans respectively and the cans are rotated about the horizontal axis to invert them and bring their tops underneath, to a bottom position, this position being that shown in Figs.- 7 and 9. The warp is then coiled in the second can and built up from the'inverted top to the inverted bottom andis passed out through the slot 36 to the inverted bottom of the third can 20. The warp is then passed through a slot 39 in this can, the cans rotated to their upright position and t-he coiling continued. This coiling method is then repeated, the warp passing alternately from the top of slot 39 to the top of aV slot 40 in can 22, from thebottoin of the slot'40 to the bottom ofa slot-42 in can 24 and from the top of slot 42 to the top of slot 44 in can 26, finally ending in the invertedy bottom of the last can 26. The cans are in effect aseries of receptacles having the'bottoms of successive receptacles arranged alternately in reversed position but, for convenience, that end of each can which is uppermost when the first can is upright will be referred toas the top of the can.

turned to their upright position and the upper portions Y46, -50 and 54 are pulled out, the yarn follows in a uniform manner in parallel. strands of the same number as the number of cans used and of a correspoiidingly shorter length than the length of the original chain. Any desired number of cans may be employed, six being shown in the present embodiment by way of example. ln this embodiment of the invention, for example, an original warp of approximately 400 ends, 9000 yards long will come out in one warp containing about 2400 ends (6 x 400) and only 1500 yards long.

The construction of the individual cans is substantially the same with the exception that the'rst, third and fifth cans may have their lower ends permanently closed since the warp will always be drawn out of these cans in the same direction that it was coiled into the cans whereas in the second, fourth and sixth cans the warp is drawn out from the opposite end from which it was coiled into the cans. The cans maybe constructed of a sheet 56 of metal or of plastic material bent to a. cylindrical form and having the two longitudinal edges 58 and 60 brought close to each other to form the longitudinal slot. The corners of' the sheet are rounded as shown at 62 and 64 to provide rounded diverging ends for the longitudinal slots. The inner lining and the edges of the cans should be very smooth.

and, if the cans are made of -a plastic ma.-

terial, the edges are preferably providedA with smooth metal edges, for the purpose of avoiding sharp or rough edges.

To attac i the lids and bottoms to the cans -the upper and lower edges of the sheet 56 are flanged slightly outwardly forming annular outwardlyprojecting flanges 66 and nositioned luos 78 and 80 on their inner l e surface positioned to be inserted one through an end of the longitudinal slots 36--44 and the other through the notches 70 i or 72 Irespectively fand rotated under the edge of the anges=66 and 68 kto hold the covers onto the cans.

In the embodiment shown in Figs. 9 to 12 ythe can'ianges 66 and 68 are omitted and the covers are attached to the cans'by means of .pins 82 and 84, projecting diametrically from opposite Vsides of the-ends of the. cans in such a manner thatrthey'maybe inserted through rightangled s'lots 86 on diametrically opposite Vsides'of thefcover iianges 78 insuch amanner as toform a bayonet joint with the pins 82 and '84. Thumb screws 88 may be provided on kthe pins `82 and 84 Vto securethe covers in place on the cans. l

Thecans may be ysupported in any suitable manner between the ends 28 'and 30'of the frame 32. "In theembodimentillustrated in Figs. 1 to 7 the 4cans Vare rigidly mounted on a yoke having a supporting beam 92, preferably of rchannel iron, on which the cans are mounted, and having end arms 94 and 96 extending forwardly at right angles to a point beyond Athe center lines of the cans. Mounted on the outer faces of the arms 94 and 96, respectively, are plates 98 and :100 having gudgeons 102 and 104 which are vjournaled in `bearings 106 and 108 in the ends 28 and 30 respectively and thus support the frame or yoke and the cans'mounted thereon. Stops110 and 112 are mounted on the lends 28 and 80 at either side of and slightly below the Lbearings 106 and 1.08 against which the arms 94 and 96 `strike when the yoke is swung through 180 degrees'to upright or inverted position to prevent the cans from 4being yrotated past the vertical and preventing the warp from lbeing thrown over theopposte -edge of the cans. A handle `114 `is also mounted on the arm 94 by means of which the yoke `may Vbe rotated.

In this construction, all of the cans are swung when any can is to be inverted or rotated back to upright position. The cans are therefore rigidly mounted on the-beam 92 -by means of brackets 120. vThe Vbrackets have a substantially fiat base 122 :pro- Y vided with ears 124 and 126 through which bolts 128 may ybe inserted to fasten the brackets to the beam 92. The bracket also comprises a 4pair -of semi-circular arms 130 and 132 extending forwardly from the base 122 to -surround the outer surface of the can, and to which the 'can is directly attached. To provide va firm attachment for the cans and avoid a stress atftheir central portions the arms are widened at their ends and at other places 1n their circumference to form attachment wings towhich the surfaces kof the cans are attached by means of rivets 136 or other ysuitable means. The ends of the arms are slightly spaced as at 138 to correspond with the slots 36-44 and -to permit the warp to pass therebetween.

A somewhat different manner of supportingthe cans isshown infthe modification of Figs. 9 to 12, in which the cans are so arranged that they ma'y rbe rotated individually, four vcans being shown by wayV of eX- ample. In this case the cans kare mounted in split encircling rings 140 having their split portions coinciding with the slots 36 to 40 of the .cans kand khaving supporting wings 142 similar to those of the brackets 120. The rings are somounted as to be rotatable relative to each other and rotatable in the end supports 28 and 30 of the supporting frame 32. F or'this purpose-each of the intermediate rings is provided at vone side with a gudgeon 144 which is journaled and supported in a projecting,.bearing 146 on 'the opposite -side of the next adjacent ring so that therings form a ychain or train extending between and "spanning the distance bec tween'theend supports'28 and 80. The end rings are provided with similar gudgeons and kbearings but the outer gudgeon 148 of one end ring 140, shown at the right in Fig. 10, is extended through -the bearing 108 and the projecting end is Vprovided with a hand wheel 150 'by means of which the gudgeon, and with itthe end can, may be rotated. In a similar manner, the projecting bearing at the other end can is provided with an extension 152 through the opposite bearing 106 of the lopposite end 28.

To hold the cans in straight, rigid position the end of the hollow bearings 146 is flattened outwardly to form a plate 154 which abuts and slides on a-complementary plate 156 attached to a boss 158 on Vthe adjacent-side of the next cansupporting ring. Each pair of plates 154-and 156 is provided with holes which `are in -alignment when the adjacent cans are inthe same position and through which a pin 160 may be passed to lock adjacent cans together. Thus, as soon-as acan Vis filled it islocked to the next adjacent empty can and Yrotated therewith as a unit. The `end plate 156 of the end can also has an abutting plate 161 .secured on a collar 162 onfthe end gudgeon 148, in such a manner as to hold the cans in position.

`With this construction, the `first two cans should be always locked together and the others may be independently rotatable and locked together as the cans are filled.

The supporting ,frame .may be of any suitable construction and may when necessary have intermediate supporting posts so arranged thatthe yarn 'connecting the coils does not cross these supports as'the cans are rotated. rl`he frames may be provided with casters or wheels 164 by which they may be transferredto the dye vats-or other apparatus.
